A line of code in the .htaccess blocks the social preview

  • Hi,

    after seeing that something was blocking the Facebook crawler (you can see HERE), I checked my .htaccess and saw a suspicious line of code:

    RewriteCond %{HTTP_USER_AGENT} !(facebookexternalhit|WP_FASTEST_CACHE_CSS_VALIDATOR|Twitterbot|LinkedInBot|WhatsApp|Mediatoolkitbot)

    This line was written by the WP Fasted Cache plugin.

    After deactivating this line, preview images of social media posts are shown.

    Could you give me information on why this happens?

    Regards
    Umberto

    This line prevents the cache from being visible to social media bots.

    But it actually blocks the preview image, the title is the description. Why?

    I could not understand.

    If you write to me what you don’t understand exactly, maybe I can give you more information.
    As I wrote above, if I leave that line of code in the .htaccess, the image preview, title and description are not displayed in social media posts. Success THIS

    However, if you delete that line of code from the .htaccess, everything goes back to normal and you can see everything in the posts.

    That line of code causes a problem. Is it clear enough now?

    Regards

    Because facebookexternalhit bot eating a lots of resources of server. We have reported so many times to facebook but no help.

    This bot crash your website and make it slower. Facebook need to fix their rules. They said it crawl every second, but it sends thousands even millions of requests to crawl only index.php page.

    why does the facebook bot need to scan your site too often?
